Spotlight vs. Backblaze
I’ve been having recent problems with spotlight’s mds process taking up a lot of cpu. In searching I found this:
… and I discovered the main culprit: Backblaze (cloud backup) was generating file lists whenever anything was change don the system, and mds was indexing them.
Sure enough that was the problem. So, if you are using Backblaze you should probably add it to the System Preferences -> Spotlight -> Privacy list.

I have received multiple requests about a plugin for EyeTV. I don’t have the EyeTV software so making a plugin required some help from someone who does. Thankfully some of those wanting the plugin were able to provide me with the info that I needed.
